It pulls 805 VA inrush and holds at 55 VA, both at 50 Hz with a cos phi of 0.3. The coil has no built-in suppressor module, so you'll need to add one externally if your circuit requires it. Closing time runs 20 to 35 ms, opening 7 to 15 ms — fast enough for standard motor starting but not for high-speed reversing applications where you'd want a DC coil. The coil dissipates 18 to 24 W at 50 Hz, which matters for panel heat buildup if you're grouping several contactors in a small enclosure. That's about 40 operations a minute — fine for a conveyor or pump cycle, but you'll hit the thermal limit if you're trying to jog a motor faster than that. The coil resistance is 6.67 ohms at 20 °C, and the closed-circuit inductance is 1.05 H. Drop-out voltage is 0.35 to 0.55 Uc at 55 °C, meaning the contactor will drop out somewhere between 49 and 77 V AC — useful to know if you're on a long cable run with voltage drop. ## Deployment context This coil snaps into a TeSys F contactor frame on a DIN rail. The 140 V AC 50 Hz control voltage is common in European panel designs, but verify your control transformer taps — a 120 V tap won't hold this coil reliably at the low end of the operational range (0.85 Uc = 119 V).","metaTitle":"Schneider LX1FG140 TeSys F Contactor Coil, 140 V AC 50 Hz","metaDescription":"LX1FG140 is a TeSys F contactor coil, 140 V AC 50 Hz, 805 VA inrush, 55 VA hold.
